All U.K. preorders of Pistorm32-lite have been assembled in house and sent out this week.  Most USA and Canadian orders have been fulfilled too

What was “before”? It doesn’t make any sense, why would it be faster with libs in rom rather than loading them from disk? And is FPU even involved in MIPS?

A couple things come to mind.

* For the A2000, try opening the case and pulling out any cards besides your 'SCSI card+hard drive'. Maybe one of the other cards is stopping the boot process. You can't hurt anything buy pulling out cards and doing a power up, just don't plug/unplug cards while the PC is powered on.
* Look for a label on the SCSI card, does it say anything like Commodore A2091, GVP HC, Trumpcard, ICD? This will help further down the line.
* When you say the A2000 turns on then off immediately, do you mean you see a Workbench screen or flashes of color? Screen colors are a built-in POST(PowerOnSelfTest) if you list the last color you see perhaps we can narrow down the boot problem.
* Depending on when you need your data you can pull the 'SCSI card+hard drive' and take it to the a Commodore club meeting or VCFED show. Someone there should be able to plug it in and tell you if it is good.
* If you're headed to Las Vegas anytime in the next 6 months, bring it along and I can test it for you.

Got an extra 50 mips out of mine, by adding 040 FPU libraries to rom. Now getting 900 Mips, .

As I wrote, the floppy drive clicks,it detects when I put a floppy in, the floppy get's read, the cracktro runs (red sector in this case), I can here the music, I can click the left mouse button to end the cracktro and then the game get's loaded.

Literally everything works except video output. And I've ruled out DENISE already by swapping it with the one from another machine which works.
